My pre-op diet is a Protein Shake for Breakfast, snack (pear, apple, or orange), lunch is a meal or salad w/lean Protein, leafy greens/veggies. No corn, potatoes or beans). Snack is another piece of fruit. dinner is another shake. If I’m hungry after dinner, I can have another shake, or 2 hard boiled eggs as a snack. I’m supposed to do this for 3 weeks. My surgery is scheduled for 9/27.
